Feb 1 (Reuters) - Scientists in Britain have been give the
go-ahead to edit the genes of human embryos for research
purposes, using a technique that some say could eventually be
used to create "designer babies".

Sharpshooting spray system cuts crop chemical use

A new spray technology that shoots a targeted droplet with
incredible accuracy could cut agricultural use of chemicals by
more than 99 percent, according to the developers. The
technology has the potential to not only save farmers money, but
also help protect the environment by dramatically reducing the
amount of chemicals that are applied. The system uses advanced
machine vision algorithms that can differentiate between healthy
and diseased crops, and then apply a droplet only to the crops
that need it.
